FLUSH-TANK FILLING VALVE.

Application filed August 4,1923. Ser`ia`1 -No. 655,617.

To the attainment of the foregoing andk other objects which will present themselves as the nature of the 'invention progresses, reference is to be had to the drawings which accompany and whichform part of this application.

In the drawings Figure 1 is a sectional view through a lilling tank for closets illustrating the application of the improvement.

Figure 2 is an approximately central vertical longitudinal sectional view through the improvement.

Figure 3 is a top plan view thereof.

Figure 4 illustrates details.

Referring now to the drawings in detail, the numeral 1 designates a filling or flush tank for closets of the usual construction.`

The water outlet 2 'in the bottom of the tank 1 is controlledby the usual valve actuated in the usual manner.

The water inlet pipe, indicated by the nu-k mei-al 3 is flanged adjacent to its bottom andv is, of course, connected to the usual water conducting pipe whereby water under pressure is let into the tank 1. The top of the inlet pipe is, of course, open and. the upper portion oi the said tank isrsurrounded by a pressure resisting chamber in the nature of a tube 4. The tube has its bottom connected to the pipe 3 and its body spaced from the side pipe in any desired manner, such for instance, as by the employment of one or more spiders 17 between the pipe and tube. The lower portion of the tube 4 is provided Vwith series of apertures 5 forming water out* lets, and the upper portion of thev said tube is threaded. Screwed on the threads is the flange of a frusto-conical cap member 6.

On thetop of the inlet pipe there is a compressible valve seat 7 for a valve 8. The valve 8 has a lower flat face which is preferably-provided with a ring washer to engage the compressible element on the seat 7. The upper portionof the valve is complemental to the inner flared surface of the cap mem ber 6. The valve 8 is provided with a` stem 9that extends through a central opening 'in the cap and to this stem there is loosely pivoteda lever 10. On the cap there is an upstan'ding arm 11 to which one end of the pivoted. Also on `the cap div lever 10 is rectly opposite the arm 11 there is an angle bracket 12, and to the upstanding or vertical arm of this bracket there is pivoted,

as at 13,the rod or Varm 14 for the float valve 15. Pivotally secured to the outer end of the lever 10 and to the inner end of the rod 14 there is a link 16.

When water from the flush tank is let through'its outlet2 the tioat will sink with the overflowing water, causing the swinging of the rod or ar1nv14 which influences the link to swing the lever 10 to raise the valve 8 to unseated position. This, of course, permits of the inflow of water through lthe pipe 3. rlhe water contacts the fiat under face ofthe cap and is thus directed downwardly into the pressure reducing chamber 4. The water finds an outlet through the apertures i5) at and adjacent to the bottom of the cham- It is believedthat the foregoing description when taken in connection with the drawings willfully set forth the construction and advantages of the improvement, but I desire it to be understood that I am entitled to such changes therefrom as `fall within the scope of what I claim.

Irlaving described the invention, I Clalm- The combination ywith a water tank having a valved outlet and a water inlet pipe, of a tubular water'pressure reducing chamber surrounding the upper part of the inlet pipe and having an open top and a closed bottom which is secured to the inlet pipe, said chamber,

at its bottom and for a distance thereabove being apertured, spiders nected with the chamber, aniv means bespacing the chamber from the inlet pipe,ra tween the chamber and rod, and actuated compressible Valve for closing the mouth of by the rise and fall of the said rod for pel- 10 the inlet pipe and seated on the top of the mittng the seating and unseating of the Chamber, a cap threadedly engaging the Valve. v
